In the classifieds here on AC, there is a person selling a couple of sets of Visaton b200 drivers, some with the phase plugs from Planet 10.
I ran those with a set of subs for 6 years, so I know they made me happy.
For what he is asking, depending on how far from Chicago you are, I would consider those for sure.
I never ran them with tweeters - with the phase plugs I never wanted for treble, and the off axis was good (to my ears).
Certainly worth consideration.
